y To all whom t may concerti:

Be it known that I, JAMEsA. DAvmss, a citizen of the United States,residing at Chicago, in the county of Cook andv State of Illinois, haveinvented a certain lnew and useful Improvement in Ash-Conveyer Systems,of which the following is a full, clear, concise, and exact description,reference being had to theI -accompanying drawings, forming a part ofthis specification.

This invention relates to ash conveyer s tems and broadlystated-isconcerned with thevprovision of means4 associated with the pipe line ofsuch a system arranged to permit the removal, replacement, andsubstitution of portions of the pipe line which in ,i the operation oft-he system become excessively worn due to the abrasive action of theashes conducted therethrough, without materially disturbing the systemor the line of pipe or conduit in which said portions are found.

Conveying systems of the class to which my present invention relatescomprise metal conduits or pipes through whlch the ashes are conducted0r moved by suction or draft of air created 'by steam jets or suitableblower or fan mechanism. While I prefer to employ my invention inconnection with an ash convcyer of the steam jet type it is equallyapplicable to other systems.

In conveying systems of the class under consideration it often, in factordinarily, is necessary t0 provide both horizontal and vertical pipelines and even oblique runs of pipe, wherefore it is very diiiicult toavoid the use of elbows or at any `rate more or less abrupt bends orturns in the pipe lines. As,

the practice in the past because of this excessive wear at the bends toprovide elbows comprising removable sections or provided with removablewear liners or backs. It has been found, however, that the excessivedirection of flow thereof is' abruptly changed or altered. It has beenabrasive action of the ashes occasioned by an abrupt chan e of thedirection in the pipe line is not con ned to the elbow or curved portionof the pipe but extends through the straight port-ion of the pipe for aconsiderable distance beyond the elbow in the direction of flow. This isprobably accounted for by the fact that the ashes after leaving theelbow or curved portion of the pipe line do not immediately resume theirnormal flow along the axis of the pipe but are for some distance carriedalong in more or less violent contact with the inner surface of the Inorder to provide for the' wear which occurs just beyond the elbow orbend as just explained, the use of a short section or length of pipethat may be removed and renewed from time to time has been suggested.However, it is ordinarily no simple matter to remove such a pipe sectionfrom the other elements of the 'pipe line and this is particularly truewhen the removable pipe length is located in a vertical riser extendingupwardly from a horizontal pipe line with which it is connected by anelbow or other curved pipe fittings. Heretofore in such a case theentire weight of the vertically disposed pipe line has been carried uponthe removable pipe length and elbow with the result that in order tolremove the elbow or the aforesaid short length of pipe or to shift theposition of the latter with respect to its associated pipe sections hasnecessitated the provision of special equipment of various kinds fortemporarily supporting those elements of the conduit above the sectionsthereof that are to be removed, re-

j placed, or shifted.

or sections therebeneath, in order that the latter may be readilyremoved, replaced, or shifted with respect to the permanent conduitsections as conditions require.

My invention is fully set forth in the del.

' means for supporting Y steam jet type, I prefer is a side elevationalview ofthe theline 4--4 of Fig. 3, and

Fig. 5 is a fragmentary view partly in ser tion and partly in elevationof certain parts of an ash conveyer system equipped with the devices ofmy invention.

Similar characters of reference refer to similar parts throughout theseveral views Referring lirst vto Figs. 1, 2 and 5, it will be notedthat the ash conveyer system comprises cast iron pipes of suitablecapacity, the abutting sections of which are provided with coperatingiiang'es secured together in any well known manner, as by bolts passingthrough registering apertures -or slots in the coperating -anges Thesystem herein shown comprises a horizontal run of pipe comprising aplurality of sections 10--10, one of which is shown in Fig. 2. Asisusually the case, the horizontal run of pipe is disposed in a trough ortunnel with the horizontal pipe sections 10-10 resting upon the tunnelfloor 11 as shown. The horizontally disposed portion of the conveyerconduit communicates with a vertical riser and I prefer to aEord thiscom munication through a long radius elbow comprising sections 12, 13,14 and 15, although my invention contemplates the use of any other formof elbow that may roverdesirable or expedient. The system being of thetoprovide 'the elbow section 15 with a steam supply pipe 16 whichcommunicates with a nozzle (not shown) carried by the section` 15 anddischarging upwardly into the conduit.

The vertical riser comprises Va removable pipe length 17 and as manysections 18 as conditions require, in the normal operation. of thesystem the ashes are carried along in the horizontal run of the conduittoward the long radius elbow and out through the vertical riser and.other conduit elements (not shown) to a suitable discharge point.

As my present invention is concerned with the provision of andpermitting the removal, replacement,v and adjustment of certain parts ofthe system shown in the 'accompanying drawings, it will be unnecessaryfor me to illustrate or describe other parts of the system, as the sameare well known to to those familiar with the art to which the inventionrelates.' v

it being understood that 'and 18 or substitute another removable sectiontherefor. Heretofore the pipe sections 18 and other conduit elementswith which it connects have been supported by the section 17 and theelbow sections, with the result that when it has been necessary toremovethe straight section 17 or one of the elbow sections, special andelaborate means has been required to support the elements of the riser,so that the parts which have been worn may be removed. My inventioncontemplates the provision of means constituting a permanent part of thesystem which contributes the required support to the conduit sectionsabove the pipe length 17 and elbow and which carries the parts above theremovable pipe length 17 independently of the elbow and pipe length 17when the pipe length 17 or elbow or any section of the latter is to beremoved.

The means for accomplishing the purpose just mentioned comprises a yokeor clamp arranged to embrace theirst conduit section above the removablep ipe length 17. Said yoke or clamp comprises a pair of strap metalmembers 19-19, each of which is conformed intermediate its ends toreceive the cylindrical surface of the conduit section 18. Thecorresponding ends of the yoke members 19-,19are brought together, as ismost clearly illustrated in Fig. 3, by bolts 20-20 and 201-20, the bolts2O and 2Oa of each pair being spaced apart to receive between them oneof the head pieces of a supporting standard presently to be described.

Disposed upon the floor 11 and situated on opposite sides of the conduitadjacent the elbow are the standard bases 21-21, each of which is in theform of an integral casting conformed to provide a cylindrical upwardlyprojecting boss 21a and an annular recess 2lb. The adjustable standardof which each base member 21 forms a part comprises a tubular element 22which may be .a length of standard gas pipe having its lower enddisposed around the boss 21a and disposed in the annular recess 21b ofthe base.

Disposed above each of the tubular elements 22 and in aXial alinementtherewith.

24:a received by the upper end of its associated tubular element 23 andan annular re- 'ral casting comprising a cylindrical boss duit of theworn sections,

portion of each of the head cess 24" in which the upper end of saidtubular element engages.` Formed in the` upper pieces 24-24 1s atransverse slot 24c which adapts the head to embrace the connected endsof the yoke or clamp members 19-19 intermediate the bolts 20 and 20,whereby said ends ofy the clamp members are secured toget-her.

Interposed between the tubular elements 22 and 23 of each standard is a.bolt 25 havlng its ends screw threadedl in opposite directions, one endof said bolt being freely disposed within the upper endof the lowertubular element 22 andits upper end freely disposed within the lower endof the tubular element 23. Threaded ,upon the bolt 25 of each standardare the nuts 2626, the washers 27-27 being interposed between said nutsand the lower and upper tubular elements as shown. It Iwill thus beseenthat adjustment of the nuts 26-26 with respect to the bolts 25changes the effective length of the latter and thereby varies the heightof the standard heads 24-24.

The vertical standards just described normally Contribute to the supportof the conriser and hold it against lateral displacement. Whenever itbecomes necessary or desirable to remove the conduit length 17 or anyone of the elbow sections, these being the parts .which are subjected tothe most excessive wear, the nuts 26-26 are adjusted to increasetheeffective length of the bolts 25-25, thereby lifting the standard heads24-24 and taking all of the weight of' the conduit section 18 and partsthereabove of'l' whereby the latter may be removed, inspected,readjusted or replaced 'with ease and without deranging the other partsof the system. A

It will be understood that the pipe section 17 may be either standardpipe orthat its walls may be of greater cross section than the otherpipes constituting the conduit to compensate for the excessive .wear towhich the pipe 17 is subjected in the tion of' the system.

It will thus be seen that I have provided simple and inexpensive meansfor spacing the permanent elements of a conduit riser from the wornparts .when said worn parts are to be renewed and for supporting theformer independently of the latter, Wherefore it is possible to removeand replace the worn parts without deranging the permanent elements ofthe conduit.

While I have described my invention as applied to the conduit of aconveyer of the steam jet type, it .will be understood that my inventionis not so limited but may be applied to various types of materialconveyers.

What I claim as new and desire to secure by Letters Patent of the UnitedStates, is:
